Silver halide color photographic light-sensitive material containing a yellow filter layer

ABSTRACT

In a silver halide color photographic light-sensitive material which includes at least one layer of each of red-, green-, and blue-sensitive silver halide emulsion layers and a yellow filter layer containing yellow colloidal silver on a support, an average grain size of at least one of the light-sensitive silver halide emulsions is 0.4 μm or less, a maximum absorption peak of yellow colloidal silver in the yellow filter layer appears at 430 to 450 nm, and 1/4 absorption of the maximum absorption at the longer wavelength side occurs within the range of 500 to 560 nm. This photographic light-sensitive material can reduce a fog by the yellow filter layer without degrading other photographic properties.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a silver halide color photographiclight-sensitive material in which a contact fog caused by yellowcolloidal silver in a yellow filter layer is suppressed.

2. Description of the Related Art

Normally, a silver halide color photographic light-sensitive materialhaving blue-, green-, and red-sensitive silver halide emulsion layers ona support has unnecessary light sensitivity in a blue light region in aspectral sensitivity distribution of the green and red-sensitiveemulsion layers.

In order to obtain good color reproducibility, however, it is preferredthat the green-sensitive emulsion layer has color sensitivity mainly inonly a green light region and the red-sensitive emulsion layer has colorsensitivity mainly in only a red light region.

Therefore, a hydrophilic colloid layer which is arranged so as to facethe support across the green-and/or red-sensitive emulsion layers isdyed in yellow to reduce an amount of blue light amount entering thegreen- and/or red-sensitive emulsion layers, thereby improving the colorreproducibility.

A component which dyes the hydrophilic colloid layer in yellow must bedischarged or discolored by development. For this reason, yellowcolloidal silver or a yellow dye such as a pyrazoloneoxonol dyedescribed in British Patent No. 506,385 or an oxonol barbiturate dyedescribed in U.S. Pat. No. 3,247,127 is normally used.

The yellow dye, however, diffuses to another layer (e.g., if the dyediffuses to a blue-sensitive emulsion layer, the sensitivity of theblue-sensitive layer is lowered) because its dyeing property is bad, orit has a poor discoloring property. Therefore, yellow colloidal silveris normally used.

This yellow colloidal silver can be prepared by various methods.

Satoshi Inoue, "Inorganic Chemistry Manufacturing Test", P. 647describes, e.g., a method of reducing silver nitrate with dextrin underalkaline conditions, a method of reducing silver nitrate with tanninunder alkaline conditions, a method of reducing silver nitrate withhydrazine, and a method of reducing silver oxide with sodium carbonateand hydrogen peroxide in the presence of a silver sol reduced withphosphorus.

When yellow colloidal silver conventionally used in a silver halidecolor photographic light-sensitive material is dispersed in ahydrophilic colloid layer such as a gelatin layer, its maximumabsorption peak appears at 420 nm to 430 nm, and 1/4 absorption of themaximum absorption at the longer wavelength side occurs within the rangeof 480 to less than 500 nm.

If the conventional colloidal silver as described above is used,however, a fog in a light-sensitive silver halide emulsion layeradjacent to a layer in which the colloidal silvers are included isundesirably increased.

A degree of the increase in fog caused by the colloidal silver differsin accordance with a grain size of light-sensitive silver halide grains.That is, as the grain size is decreased, the fog is increased. Inparticular, if a grain size of silver halide grains in a light-sensitivesilver halide emulsion layer adjacent to a yellow colloidal silver layeris small, a fog is significantly increased.

On the contrary, graininess of a light-sensitive silver halide emulsionis normally improved as a grain size of the emulsion is decreased.Therefore, in order to improve the graininess, studies for increasing asensitivity/grain size ratio have been continuously made by thoseskilled in the art. According to the studies made by the presentinventors, however, as the grain size of silver halide grains isdecreased, the fog caused by colloidal silver used in a yellow filterlayer is increased, as described above. Especially when the grain sizeis 0.4 μm or less, an increase in fog is large.

The following method is known as a method of suppressing the fog. Thatis, Published Examined Japanese Patent Application No. 59-47305discloses a method of adding I⁻ to a hydrophilic coloid layer containingcolloidal silver or an adjacent non-light-sensitive layer, and Zhun,Nauch, i Priklad, Fot, i Kinematografii, 6, 2256 (1961) discloses amethod of adding various non-diffusing reducing agents to a colloidalsilver-containing filter layer.

When I⁻ is added as described above, however, development of alight-sensitive silver halide emulsion is suppressed, or I⁻ isaccumulated in a bleaching and fixing solution used in a developmentstep to reduce a bleaching and fixing speed.

In the method of adding the non-diffusing reducing agent to the filterlayer, a bleaching speed of colloidal silver in a development step isreduced, or a fog of a light-sensitive silver halide emulsion isincreased when a light-sensitive material is stored underhigh-temperature and high-humidity conditions.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a silver halidecolor photographic light-sensitive material which comprises at least onelayer of each of red-, green-, and blue-sensitive silver halide emulsionlayers and a yellow filter layer containing yellow colloidal silver,wherein an average grain size of at least one of the light-sensitivesilver halide emulsions is 0.4 μm or less, a maximum absorption peak ofyellow colloidal silver in the yellow filter layer appears at 430 to 450nm, and 1/4 absorption of the maximum absorption at the longerwavelength side occurs within the range of 500 to 560 nm.

When the color light-sensitive material of the present invention is acolor light-sensitive material for picture taking with camera, it ispreferred that the maximum absorption peak of yellow colloidal silver inthe hydrophilic colloid layer appears at 430 to 445 nm and the 1/4absorption of the maximum absorption at the longer wavelength sideoccurs within the range of 500 to 540 nm.

When the color light-sensitive material of the present invention is aprinting or duplicating color light-sensitive material, it is preferredthat the maximum absorption peak of yellow colloidal silver in thehydrophilic colloid layer appears at 430 to 445 nm and the 1/4absorption of the maximum absorption at the longer wavelength sideoccurs within the range of 500 to 550 nm.

The silver halide color photographic light-sensitive material of thepresent invention can reduce a fog caused by the yellow filter layercontaining yellow colloidal silvers without degrading other photographicproperties.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A wavelength of a maximum absorption peak and a wavelength at which 1/4absorption of the maximum absorption occurs of yellow colloidal silverin a hydrophilic colloid layer of the present invention are obtained asfollows.

That is, a coating aid and a hardening agent are added to a gelatindispersion of yellow colloidal silver, and the resultant material iscoated on a transparent support. This coated sample is bleached andfixed to obtain a desilvered sample. By using the desilvered sample as areference, spectral absorption of a yellow colloidal silver coatedsample is measured by a spectrophotometer.

Although a coating silver amount of yellow colloidal silver of thepresent invention is not particularly limited, it is preferably 0.001 to1.2 g/m², and more preferably 0.01 to 0.6 g/m².

Yellow colloidal silver for use in the present invention can be preparedas follows. A preparation method, however, is not limited to thefollowing one.

1. Dextrin (0.1 to 10 kg) is dissolved in distilled water (5 to 100 l),and aqueous hydrogen peroxide solution (31%, 0.01 to 3 l) is added tothe solution. NaOH is used to adjust a pH to 10 to 13, and a silvernitrate solution (AgNO₃, 1 kg) is added. A temperature is preferably setbetween 25° C. to 70° C. At a higher temperature, yellow colloidalsilver having a maximum absorption peak at a longer wavelength isprepared.

2. NaBH₄ (0.02 to 2 kg) is dissolved in distilled water, NaOH is used toadjust a pH to 10 to 13, and a silver nitrate solution (AgNO₃, 1 kg) isadded.

3. A pH of a silver nitrate solution (AgNO₃, 1 kg) is adjusted to 10 to13 by NaOH, and hydroquinone (0.01 to 10 kg) and Na₂ O₃ (0.05 to 20 kg)are added to the solution to prepare yellow colloidal silver having amaximum absorption peak at a longer wavelength.

After yellow coloidal silver for use in the present invention isprepared or when a yelow filter layer coating solution is prepared,chlorine ions or bromine ions may be added by using, for example, analkaline metal chloride, ammonium chloride, an alkaline metal bromide orammonium bromide.

Alternatively, iodine ions may be added by using, for example, a smallamount of an alkaline metal iodide or ammonium iodide.

In the present invention, an average grain size of a silver halide usedin at least one emulsion layer is 0.4 μm or less, and preferably, 0.08to 0.35 μm.

This silver halide is silver iodobromide, silver iodochloride, or silveriodochlorobromide containing about 30 mol% or less of silver iodide.Silver iodobromide containing about 2 mol% to about 25 mol% of silveriodide is most preferable.

A silver halide grain in a light-sensitive silver halide emulsion mayhave a regular crystal such as a cubic, octahedral, or tetradecahedralcrystal, an irregular crystal such as a spherical or tabular crystal, acrystal defect such as a twine plane, or a combination thereof. Althoughthe emulsion grains may be either monodisperse or polydisperse, amonodispersed emulsion having a 20% or less of a variation coefficientis preferred.

The silver halide emulsion for use in the present invention can beprepared by using methods described in, for example, Research Disclosure(RD), No. 17643 (1978, December), PP. 22 and 23, "I. EmulsionPreparation and Types", and RD Nc. 18716 (1979, November), PP. 648; P.Glafkides, "Chimie et Physique Photographique", Paul Montel, 1967; G. F.Duffin, "Photographic Emulsion Chemistry", Focal Press, 1966; and V. L.Zelikman et al., "Making and Coating Photographic Emulsion", FocalPress, 1964.

Monodispersed emulsions described in, e.g., U.S. Pat. Nos. 3,574,628 and3,655,394, and British Patent No. 1,413,748 are also preferable.

A tabular grain having an aspect ratio of about 2 or more can be used inthe present invention. The tabular grain can be easily prepared bymethods described in, e.g., Gutoff, "Photographic Science andEngineering", Vol. 14, PP. 248 to 257 (1970); U.S. Pat. Nos. 4,434,226,4,414,310, 4,433,048, and 4,439,520, and British Patent No. 2,112,157.

A crystal structure of the silver halide grain may be uniform, may havedifferent halogen compositions in its inner and outer portions, or maybe a layered structure. Alternatively, a silver halide having adifferent composition may be bonded by an epitaxial junction, or acompound other than a silver halide such as silver rhodanide or leadoxide may be bonded.

In addition, a mixture of grains having various crystal shapes can beused.

The emulsion grain may be either a surface latent image type in which alatent image is mainly formed on its surface or an internal latent imagetype in which a latent image is mainly formed inside the grain.

The silver halide emulsion is normally subjected to physical ripering,chemical ripening, and spectral sensitization and then used. Additivesused in these steps are described in Research Disclosure Nos. 17643 and18716, and they are summarized as follows.

The present invention can be applied to various color light-sensitivematerials.

Typical examples are a color reversal film for a slide or TV, colorreversal paper, and an instant color film.

These compounds can beused in a combination of two or more thereof in accordance withapplications.

In order to perform reversal development, black-and-white development isperformed and then color development is performed. As a black-and-whitedeveloper, well-known black-and-white developing agents, e.g., adihydroxybenzene such as hydroquinone, a 3-pyrazolidone such as1-phenyl-3-pyrazolidone, or an aminophenol such asN-methyl-p-aminophenol can be used singly or in a combination of two ormore thereof.

The pH of the color and black-and-white developers is generally 9 to 12.

In addition to the above components, a formalin antifoggant A-3, agelatin hardener H-3, and a surfactant were added to each layer.

Preparation of Emulsions A and B

A silver bromide cubic emulsion having an average grain size of 0.15 μmwas prepared by a controlled double jet method and fogged at a low pAgby using hydrazine and gold complex salt (to be referred to as anemulsion A hereinafter).

250 Å-thick shells of silver bromide were formed on the surface of thegrains of the emulsion A prepared as described above to prepare anemulsion B.

Preparation of Sample 102

A sample 102 was prepared following the same procedures as for thesample 101 except that a grain size of light-sensitive silver halidegrains in the layers 3, 7, and 11 of the sample 101 were set to be 0.45μm.

Preparation of Sample 103

A sample 103 was prepared following the same procedures as for thesample 102 except that yellow colloidal silver B was used in place ofthe yellow colloidal silver A of the layer 10 of the sample 102.

Preparation of Sample 104

A sample 104 was prepared following the same procedures as for thesample 101 except that potassium iodide was added to the layer 10(yellow filter layer) of the sample 101 such that a coating weightbecame 1.0×10⁻² g/m².

Preparation of Samples 105-107

Samples 105 to 107 were prepared following the same procedures as forthe sample 101 except that colloidal silver listed in Table 1 was usedin place of the yellow colloidal silver A in the layer 10 of the sample101.

The samples 101 to 107 prepared as described above were exposed withwhite light through a continuous optical wedge and subjected to thefollowing development processing, and densities of cyan, magenta, andyellow were measured. At this time, a maximum density (Dmax) and arelative sensitivity with a density of 1.0 were obtained. In the case ofa color reversal light-sensitive material, as the Dmax is increased, afog is reduced. In addition, remaining silver amounts of the developedsamples were measured to compare desilvering properties.

In order to compare graininesses, a value 1,000 times an RMS graininessat a portion having a density of 1.0 was obtained. The results arelisted in Table 1.

2nd Washing Solution

Tap water was supplied to a mixed-bed column filled with an H typestrongly acidic cation exchange resin (Amberlite IR-120B, available fromRohm & Haas Co.) and an OH type anion exchange resin (Amberlite IR-400)to set the concentrations of calcium and magnesium to be 3 mg/l or less.Subsequently, 20 mg/l of sodium isocyanurate dichloride and 1.5 g/l ofsodium sulfate were added, thereby mother and replenishing solution wereobtained. The pH of the solution fell within the range of 6.5 to 7.5.

As is apparent from the results shown in Table 1, according to thepresent invention, the Dmax is increased higher (fog is decreased lower)than in the comparative examples without degrading the graininess,sensitivity, and desilvering performance.

EXAMPLE 2

The following layers 1 to 14 were formed on the upper surface of a papersupport (thickness=100 μm) whose surfaces were laminated withpolyethylene, and the layers 15 and 16 were coated on its lower surface,thereby preparing a color photographic light-sensitive material. Thepolyethylene at the layer 1 side contained titanium oxide as a whitepigment and a small amount of ultramarine blue as a bluing dye(chromaticity by L*, a*, and b* systems on the surface of the supportwere 88.0, -0.20, and -0.75, respectively).

Light-Sensitive Layer Compositions

Components and coating weights (in units of g/m²) will be presentedbelow. Note that silver halides are represented by silver-convertedcoating weights. Emulsions used in the respective layers were preparedfollowing the same procedures as for an emulsion EM1 to be describedlater. Note that a Lippmann emulsion not subjected to surface chemicalsensitization was used as an emulsion in the layer 14. Structuralformulas of compounds described in the compositions are listed in Table5 to be presented later.

Preparation of Emulsion EM-1

Aqueous solutions of potassium bromide and silver nitrate weresimultaneously added to an aqueous gelatin solution under vigorousstirring at 75° C. over 15 minutes to obtain octahedral silver bromidegrains having an average grain size of 0.40 μm.3,4-dimethyl-1,3-thiazoline-2-thion, sodium thiosulfate, and chloroauricacid (tetrahydrate) were sequentially added in amounts of 0.3 g, 6 mg,and 7 mg per mol of silver, respectively, to the resultant grains andthen the grains were heated at 75° C. for 80 minutes, thereby performingchemical sensitization. The resultant grains were used as a core andprecipitated in the same precipitation environment as in the first time,thereby finally obtaining an octahedral monodispersed core/shell silverbromide emulsion which contains the grains having an average grain sizeof 0.7 μm. A variation coefficient in grain size was about 10%. Sodiumthiosulfate and chloroauric acid (tetrahydrate) were added in amounts of1.5 mg per mol of silver, respectively, to the emulsion and then theemulsion was heated at 60° C. for 60 minutes to perform chemicalsensitization, thereby obtaining an internal latent image type silverhalide emulsion.

In each light-sensitive layer, ExZK-1 and ExZK-2 wire used as anucleating agent in amounts of 10⁻³ and 10⁻² wt% with respect to thesilver halide, respectively, and Cpd-22 was used as a nucleationaccelerator in an amount of 10⁻² wt% with respect to the silver halide.In addition, in each layer, Akanol XC (Du Pont de Nemours, E.I., Co.)and sodium alkylbenzenesulfonate were used as an emulsifying/dispersingagent, and succinate and Magefac F-120 (DAI NIPPON PRINTING CO., LTD.)were used as a coating aid. In silver halide- and colloidalsilver-containing layers, Cpd-23, Cpd-24, and Cpd-25 were used as astabilizer. This sample was used as a sample 201.

Preparation of Sample 202

A sample 202 was prepared following the same procedures as for thesample 201 except that an average grain size of the light-sensitivesilver halide grains in the layers 3, 6, and 11 of the sample 201 wasset to be 0.5 μm, respectively.

Preparation of Sample 203

A sample 203 was prepared following the same procedures as for thesample 201 except that potassium iodide was added to the layer 9 of thesample 201 such that a coating weight became 0.7×10⁻² g/m².

Preparation of Samples 204-206

Samples 204 to 206 were prepared following the same procedures as forthe sample 201 except that colloidal silver shown in Table 2 was used inplace of the yellow colloidal silver A in the layer 9 of the sample 201.

Preparation of Samples 207 and 208

Samples 207 and 208 were prepared following the same procedures as forthe samples 204 and 205 except that potassium bromide was added to theyellow filter layers of the samples 204 and 205 such that a coatingweight became 0.6×10⁻² g/m², respectively.

The samples 201 to 20B prepared as described above were exposed withwhite 1light through a continuous optical wedge and subjected to thefollowing development, and cyan, magenta, and yellow densities weremeasured. A developing speed is decreased as a maximum density (Dmax) isdecreased, and a fog is increased as a minimum density (Dmin) isincreased.

In addition, remaining silver amounts of the developed samples weremeasured. As the remaining silver amount is increased, a desilveringspeed is decreased.

The results are listed in Table 2.

Washing Solution

Tap water was supplied to a mixed-bed column filled with an H typestrongly acidic cation exchange resin (Amberlite IR-120B, available fromRohm & Haas Co.) and an OH type anion exchange resin (Amberlite IR-400)to set the concentrations of calcium ion and magnesium ion to be 3 mg/lor less. Subsequently, 20 mg/l of sodium isocyanurate dichloride and0.15 g/l of sodium sulfate were added, thereby mother and replenishingsolution were obtained. The pH of the solution fell within the range of6.5 to 7.5.

In addition to the above components, a stabilizer Cpd-23 (0.07 g/m²) foran emulsion and a surfactant Cpd-33 (0.03 g/m²) were added as coatingaids to each layer.

Preparation of Sample 302

Sample 302 was prepared following the same procedures as for the sample301 except that an average grain size of light-sensitive silver halidegrains in the layers 2 and 6 of the sample 301 was set to be 0.5 μm.

Preparation of Sample 303

A sample 303 was prepared following the same procedures as for thesample 301 except that potassium iodide was added to the layer 11 of thesample 301 such that a coating weight became 1.0×10⁻² g/m².

Preparation of Samples 304-306

Samples 304 to 306 were prepared following the same procedures as forthe sample 301 except that colloidal silver shown in Table 3 was used inplace of the yellow colloidal silver A in the layer 11 of the sample301.

Preparation of Sample 307

A sample 307 was prepared following the same procedures as for thesample 304 except that potassium iodide was added to the layer 11 of thesample 304 such that a coating weight became 1.0×10⁻³ g/m².

The samples 301 to 307 prepared as described above were exposed withwhite light through a continuous optical wedge and subjected to thefollowing development, and cyan, magenta, and yellow densities weremeasured.

Relative sensitivities of cyan, magenta, and yellow at a portion higherby a density of 0.2 than fog (minimum densities) were obtained.

Remaining silver amounts of the above developed samples were measured.In order to compare graininesses, a value 1,000 times an RMS graininessat a portion of a density of 1.5 was obtained.

The results are summarized in Table 3.
